Full Inbox: Roundcube

[DonY81]

Im new here but having a few issues with my round cube webmail.
I had about 1200 emails and my inbox was at 90% so I deleted almost half of them now down to 650 emails and now its at 80%.
I cannot select an option to see email size.

surely with 600 emails it shouldn't be at 80%.

Has anyone got any ideas on how to resolve this as im now at a loose end completely.

p/s sorry if ive posted this here wrongly.

Emails are different sizes, check for email with large attachments.
